Hi,

The attached hex files looks right to me, and indeed seem to work on my nRF52 DK (PCA10040).

However, the command I used for programming was slighlty different from that in the attached text file: The last option should be "--reset" (with two dashes) and not "-reset" (with one dash). With the wrong version of the option, the board is not reset after programming. Manually resetting it, or correctly applying --reset, makes it work.

I find it a bit strange that nrfjprog doesn't give any error response on the erroneous "-reset" option. If anything I would have expected it to treat r, e, s, e and t as individual short form options (which should both apply reset (-r) and trigger error on wrong use of the -s parameter.) The behavior looks like silently dropping wrongly formatted options, which I consider a bug. I have reported it internally for the nrfjprog team to look into and hopefully patch for a future nrfjprog release.

Regards,
Terje
